Philip Seymour’s Hoffman’s estranged girlfriend emerged from her West Village home Tuesday to make funeral arrangements for the actor following his tragic death Sunday from an apparent heroin overdose.

Mimi O’Donnell – the mother of Hoffman’s three adorable young children – would not comment as she left the Frank E. Campbell Funeral Home on the Upper East Side.

But sources said there will be a private wake for family and friends at the 116-year-old funeral home at 1076 Madison Ave. Thursday from 5 to 9 p.m.

A funeral will follow Friday – either at 11 a.m. or noon – at St. Ignatius of Loyola at 980 Park Ave., the same church where services were held for Jackie Onassis in May 1994.

O’Donnell was joined by Bella Wing-Davey, the British indy filmmaker who was also Hoffman’s personal assistant.

They left O’Donnell’s Jane Street apartment in a black GMC Yukon about 9:20 a.m. and drove to the funeral home.

The grieving O’Donnell, in a long, black coat, had her hood pulled down over her face as she left her apartment.

Wing-Davey had arrived about 30 minutes earlier after taking a cab from her own place on Washington Square West.

Wearing a black coat, jeans, boots and a yellow scarf, Wing-Davey tried to hide her face with her scarf as she walked to the waiting cab.

Meanwhile, visitors continued to stop by O’Donnell’s apartment with food and gifts for her and her three children.

“Third Watch” actor Bobby Cannavale stopped by with a bag and then left a short time later.

Six large boxes of Pizza from Eli’s Bread were delivered to the apartment as well.

O’Donnell had thrown Hoffman out of their apartment about three months ago because of his drug use, sources said.

“It was known that he was struggling to stay sober, and his wife had given him some tough love and told him he needed some time away from the kids and to get straight again,’’ a Hollywood source told The Post.

It was O’Donnell who first suspected something was amiss when Hoffman failed to show up Sunday morning to meet their kids at a neighborhood playground.

She called Hoffman’s playwright buddy David Bar Katz, who then went to Hoffman’s apartment at 35 Bethune St. – just two blocks from O’Donnell’s – with Wing-Davey.

They found his body in the bathroom with a needle still stuck in his arm and empty bags of heroin nearby.
